Programming note: Tune in to CNN tonight at 8 p.m. ET to watch "The Bully Effect."

The new AC360° documentary, "The Bully Effect," follows the lives of families who were featured in the eye-opening film "Bully," and also the filmmaker Lee Hirsch. CNN producers dedicated a year to tracing their journeys of self-discovery, and the transformative experiences they had as a result of the movie.

They have become empowered through telling their stories of struggle and perseverance. In their own unique ways, they're on the front lines of the movement to stop bullying. As you can see in"The Bully Effect," they were victims who are now inspirations and advocates for others suffering in silence.

There has been a remarkable outpouring of support and responses to the documentary. Viewers have taken to Twitter, Facebook, Instagram, Google+, AC360.com, and iReport to share their own stories, advice, and words of encouragement. It's a testament to the changes happening around the country in large and small communities, led by adults and kids who believe, like Anderson Cooper does, that enough is enough.
